Green Roofs - Living Architecture Monitor - Fall 2019 - 25
TABLE: GLOBAL GREEN ROOF AREA AND DENSITY, 2015
The table below ranks cities in terms of square metres of green roof per inhabitant, which is in line with the World Health
Organization's urban health indicator of green space per urban inhabitant. This is a more appropriate metric when demonstrating how
well cities are performing in terms of green roof provision. The figures reveal that while certain cities have an impressive total green
roof area, the density - or sq m2 per inhabitant - is actually relatively low. London's CAZ, on the other hand, has a total green roof
area that is slightly below average when compared with most other cities, but has a much greater square metergae per citizen.
